Hi Marina,
How wonderful that you have created the opportunity to take EFT into the school!
I would certainly stress the value of EFT in relieving test anxiety. It is ideal if EFT can be introduced early in the year to work on students' apprehensions about the subject matter. Some students already believe that reading or math is "too hard" and, therefore, feel they have no chance for mastery. I like to work with those students early, identifying why they think it is too hard and tap on those issues to clear them. This allows the students more freedom to learn the subject matter with confidence. Then I go back into the classrooms the weeks before we do our mandated state testing to tap on test anxiety, stress, and nervousness. I explain to the students that when they are calm and relaxed it is much easier for their brains to function as wonderfully as they are designed to do. I teach the students how to tap for themselves and encourage them to take breaks during the test to tap if they feel they are getting tired or stressed. Many of my teachers have learned to tap, which is great for them to relieve their own stress, as well as to tap with their students before introducing a new concept or to relieve stress or fear.
Hope this helps somewhat! I wish you well!
